The bill is part of a wider programme of reform which aims to cut corruption and create a more unified civil service, satisfying the preconditions of South Africa's National Development Plan.
Sisulu plans to set up a school of government to train and develop government employees by October, which will form the basis of this training should the bill be passed. She claimed this will "entrench professionalism" in public services, and has previously said that new government employees would not qualify for promotion or pay rises without this training. Public sector unions in the country have already agreed to compulsory induction courses for new public servants.
However, the public service spokesman of South Africa's opposition party the Democratic Alliance, Kobus Marais, has questioned where the budget for the new school of government would come from. He added that "nothing that we have seen so far" has suggested that unifying the three departments would offer better value for money.
At present, 1.3 million public servants are employed in 45 national and 207 provincial departments in South Africa, and a further 300,000 staff in 270 local municipalities.
According to Business Day Live, the bill is due to be tabled in parliament this week.
